[Also in Divisions G3 and H3] A D.C. to D.C. converting circuit comprises an oscillator such as a multi-vibrator 1 and 2 of adjustable mark/space ratio controlling a switching device 3 supplied with the D.C. input and whose output is rectified and smoothed. As shown, the anode circuit includes a transformer 10 supplying a rectifier 12 and smoothing elements 13, 15. A diode 14 is also included. The multivibrator and valve 3 are fed from a common D.C. source and resistors 6, 7 provide a variable resistance to vary the mark/space ratio of the multivibrator. In a modification the transformer is replaced by a resistance capacity coupling (Fig. 3, not shown). In a further modification the multivibrator is replaced by an A.C. source in series with a variable D.C. source. In Fig. 5, automatic stabilization is achieved by controlling the space/mark ratio by a feedback arrangement wherein the output is fed back to terminals 32, 33 of a Wheatstone bridge arrangement including a glow discharge lamp 27 and resistances 28, 29, 30 and 31 of which 30 is variable. The diagonal of the bridge comprises valves 36, 37 whose grids are connected at points 39 and at a slider 35 and the output is fed to modulate at 41 oscillations from an oscillator 42 whose output is rectified at 43 and applied to the grid of valve 1 in the multivibrator.

Filed: 1974-09-11
Abstract: 1469024 Measuring temperature electrically UNITED STATES ENERGY RESEARCH & DEVELOPMENT ADMINISTRATION 11 Sept 1974 [1 Oct 1973] 39687/74 Heading G1N [ Also in Division H1] A charge storage device for use as a temperature sensor comprises an electronically insulating ionic conductor including a dominant conductivity increasing dopant and a pair of spaced electrodes thereon, the material of the electrodes, the ionic conductor and dopant being selected such that the electronic conductivity of the electrodes is less than the ionic conductivity of the ionic conductor so as to prevent injection of charge carriers from the electrodes into the dielectric. Alternatively where the conductivity of the electrodes is greater, a film of material of resistance high enough to prevent such charge carrier injection is interposed between the electrodes and the ionic conductor. The dopant material should be such that there is a dominant dopant whose concentration is at least six times that of all other dopants. It is stated that the rate of charging or discharging of the device is temperature dependent. As shown Fig. 5, the ionic conductor 15 has electrodes 12, 13 and is connected to an A.C. source 40. Variations in ambient temperature cause variations in charging or discharging rate, and a corresponding variation in current is measured by voltmeter 41, tuned to avoid spurious background pick-up characteristics of the original frequency by device 43.

Moisture and fertilizers are added in the machine hood or at its forward end. In a modification upper and lower high speed shafts are provided with tines arranged so that compost is thrown from the centre outwards and from the edges inwards. The tines such as 10, Fig. 1, have their leading edge 12 tangential to a shaft in a cut-out 16 in the base and are of sheet metal with a rounded tip 22. The tines may be in pairs or may be formed of welded rods to provide a tangential leading edge or may be bars passing through the shaft.

As shown in Fig. 4, the lug 30 is secured to the separator 29 by a pin 31, a ring 33 connected to the pull tab 34, being slidingly received in the slot 32. In a modification, Fig. 7, the lug 30a is formed of a filament of rigid material and has its ends 35 inserted in a bore 36 in the separator 29. In a further modification, Fig. 8 not shown, the slotted lug 30b also projects beyond the flared front end 24 of the slider so that the pull tab  (34) can be turned over this front end 24 to be invisible when the fastener is closed.

Title: Improvements in winding
Inventor: MACKIE JOHN KAY PRINGLE
IPC: D01H1/04
Filed: 1966-09-08
Abstract: 1,202,205. Package. JAMES MACKIE & SONS Ltd. 6 Sept., 1967 [8 Sept., 1966], No. 40223/66. Heading B8M. [Also in Division D1] A package 15 of synthetic plastics tape drawn from a controlled speed supply source is wound on a non-rotary support 34 by a winding guide 47 (e.g. on a flyer 12) driven round the axis of the support so as to insert one turn of thrust for each revolution of the guide. Thus when the tape is drawn off over-end e.g. in a loom, the drawn-off tape is twistless. As shown spindle 14 carrying the flyer is driven from a pulley 26 which transmits drive to a clutch plate 29 on the spindle through friction pads 28. Pads 28 are radially movable so that as the package grows the torque applied to the spindle is lessened and the tension in the tape is kept constant. Other types of slipping drive may be used. The tape passes to the flyer over a pulley 45 close to the top shoulder 46 of the flyer; thus each twist inserted in the tape is localized. The flyer is provided with a selfthreading guide roller 47 and a co-operating pivoted wire arm which lays the tape on the package. The packags build is derived from the reciprocation of a rail 20 and associated shaft 40, the reciprocation being transmitted by a bar 38. To obtain shaped package ends shaft 40 is intermittently rotated so that a gear thereon engaging a rack on bar 38 shifts bar 38.

Abstract: 1,124,753. Seaming non-metallic sheet material. TILLOTSONS (LIVERPOOL) Ltd. 4 Oct., 1965 [3 Oct., 1964], No. 40366/64. Heading B5K. [Also in Division B8] Electrodes 14-17 applying an R.F. electric field to seal the end flaps 10 of a carton 12 are disposed as shown so that the electrodes 14, 15 hold the flaps closed while the electrodes 16, 17 support the carton. The arrangement is particularly suited to the closure of cartons containing electrically conducting articles such as a metallic foil tray 38, since the R.F. electric field is applied only in the region of the end flaps, and is therefore not distorted by such contents. Cartons 12 may be moved through the apparatus by means of pushers 20 on an endless belt 18, first passing a roller (28), Fig. 2 (not shown), which applies glue to the flaps, and then passing through a cam arrangement which folds the flaps down prior to entry between the electrodes (15, 17, &c.). After subjection to the R.F. electric field, the carton passes between rails (34, 36) where the glue cools and hardens. The cartons may be coated with wax or thermoplastic material, in which case the glue generates sufficient heat in the electric field to melt the coatings, and so permit the glue to adhere to the carton material. The electrodes 14-17, Fig. 1, may be connected in parallel as shown, or in series.

The sleeve and oil also serve to conduct heat away from the weld region and prevent heat from reaching the cable core. The sheath 22 and enclosure 36 may be of metal or metal alloy.

Abstract: 1356902 Train control system INTERNATIONAL STANDARD ELECTRIC CORP 7 Sept 1972 [10 Sept 1971] 41542/72 Heading B7N  In a system for controlling railway traffic in an area in response to a signal indicating an overheated axle box on a train in the area, the overheated axle box detectors can be at the trackside or on the trains. Each axle box on the train including locomotive T and rail wagons W1, W2 is provided with two detectors F1, F2 or F3, F4 or F5, F6, one of which provides an output when the axle box temperature is critical and the other at a temperature approaching the critical value. Signals from the detectors, and axle type and vehicle position signals, are transmitted via a line connecting the rail vehicles to the locomotive and are transmitted from the locomotive by transmitter S1, either by radio or lineside wire, to a receiver E1 at a central control. The output from the receiver is fed via a converter V1 to an evaluating and output device A and data processor EDV. The processor determines, taking into account all the traffic in the area, the speed and the place and time of stopping of the train with the overheated axle box and also control data for the other trains in the area. The output device A passes the data as control instructions which are passed by transmitting devices S2 to the trains. Where the detectors are at the line side the information is passed to the central office which issues control signals to signal boxes STW controlling line side signals.
